Does Commerce Heights have drinking water violations?
EPA's records list 8 violations for this system; none is health-based, and the most recent began in June 1997. The violations listed here began between June 1991 and June 1997. By type: 8 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 7 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.
